43 Claims.

The invention relates to the manufacture of slide fasteners, and more particularly to a machine for forming slide fastener scoops or elements and setting them on a tape.

Efforts have been made for many years to produce a satisfactory slide fastener of small size (the so-called No. 2 fastener), especially for use in clothing. Machines have been developed for this purpose, but for various reasons they have not been really satisfactory. The fasteners produced have been lacking in strength and durability, because of the manipulations to which the scoops are subjected during their forming and setting. Furthermore, the machines have been large, complicated and expensive, requiring numerous skilled operators, and have been subject to breakdowns requiring costly repairs.

The primary object of the present invention is to provide a machine for the manufacture of slide fastener elements which overcomes the disadvantages of the devices heretofore known.

Another object of the invention is to provide a machine which so manipulates the scoops, during their formation and setting, that they are not weakened, so that the resulting fastener, even if of small size, is strong and durable.

A further object of the invention is to provide a machine of such simple and small construction that it is inexpensive and easy to operate and repair, being so arranged that several of the machines can be controlled by a single operator.

In general, the invention contemplates a machine in which scoop blanks are sheared from a Y-shaped wire, are then simultaneously gripped and formed at a first station by an oscillating die and punch, and are then carried by oscillation of the die and punch to a second station where they are clamped on the tape. The feeding of the head of the tape between the legs of the scoop and the pressing of the legs together on this bead are controlled by the oscillation of the die and punch.

Further, I provide means for feeding proper lengths of wire to the blank shearing device, means for feeding the tape step by step, and means for intermittent rapid feed of the tape to provide gaps between successive groups of fasteners.

which is s ecuredto block 68 byjscrew. and th e vertical position of which can be adjusted by a block 84 having an inclined surface and held in position by bolt 85 between block 68 and knife carrier 80-. The movable knife 88, shown in detail in Fig. 11, has a downwardly projecting point adapted to engage between the legs of the Y-shaped wire and notches 92 for receiving the ends of these legs. This knife is secured to the knife carrier 80 "by a screw E4, the end of which engages a spring strap 96 on the other face of the knife carrier which acts to prevent turning of the screw and to ensure the proper holding of the knife 83 in position on the carrier.

Shaft I8 on its other end carries a crank memher (see Figs. 1, 2b and 5), which through crankipin' 1-02 -and block H34 engages in forked arms of lever 1 98 mounted on shaft I It]. This level through adjustable threaded connection I i2 drives a lever H4 having at its end a segmental rack portion H6. Rack H6 engages a gear H8 io m ns a a t f th s pe o mi and setti mec anism new t he de r be Referring, particularly to Figs. 15 to 20, gear H8 is mounted to turn to a limited extent one shaft [20. Limitation of the movement is tal .vided by the formation in the inner periphery of gear H8 of two opposed notches I2 2 sang. .18) within which engage th e erids of a key I21 passing through and secured in shaft I20. Shaft I20 is mounted in bearings J25 mth na eand carries at its inner endan annui rmemter 1,2 8 forming a part of the rorm nganasetnn' drum.

L64 pnjshmgf it st the 'sur ce carrier I36 to move along 'in' 'norjnalfoperation I with the drums until its movement is'stopped in a manner to be described below.

Stationary knife member 64 has a downward extension I60 located in the position shown particularly in Figs. 17A to 17D between the peripheries of the discs I54. This extension lies in the path of the outer part I40 of the carrier I36 so as to limit its movement in a counterclockwise direction.

,On the front face of the machine is arranged the mechanism for setting the scoop element on the tape. This is shown particularly in Figs. 27 to 29. Projecting from the front face of the casing 4 are arms I in which are pivoted at I1I levers I12. These levers have at their outer ends recesses in which engage coil springs I14 resting with their other ends against the casing 4, so that the inner ends of levers I12 which are located opposite the drum mechanism are urged inwardly towards this drum. Pivoted at I16 on the inner ends of arms I12 are tape gripping and scoop clamping levers or side tools I18. These side tools have on their inner faces tape gripping members I80 formed of spring sheet metal and having at their free ends, that is at the ends nearest the drum mechanism, recessed grooves I82 facing towards each other. 0

On the lower part, adjacent the drum mechanism, side tools I18 carry plates I84 providing a stop mechanism to operate in the manner to be described. These stop members I84 are likewise of spring metal and their inner ends are secured to the side tools I18. Just above stop members I84 side tools I18 have projecting hardened faces I86. The free ends of side tools I18, as shown in Fig. 27, engage between the outer parts of the radial faces of disc I54.

Drums I28, I32 have on their peripheral faces, as shown in Fig. 26, flat cam portions I88. The inwardly projecting rims of discs I54 likewise have on their radial faces cam portions I90, shown in developed form in Fig. 25. These cam surfaces are located slightly behind (counterclockwise in Figs. 17A to 17D) the punch member I48.

The tape feeding and guiding mechanism is shown principally in Figs. 12 to 14. The tape I82 is fed downwardly from the top of the machine along its front face through a suitable guide I94 between side tools I18 to the tape feeding mechanism (see Figs. 1,. 2 and, 12). This mechanism consists of two opposed rollers I86,

I98 connected to turn together by gearing 200.

Roller I96 is mounted on a shaft 202 which may be turned by hand wheel 204. Shaft 202 1s mounted in the frame 4 and carries on its inner end a gear 206 and a ratchet wheel 208. The ratchet wheel is engageable by a pawl 2I0 carried on an arm 2I2 pivoted on shaft 2I4 of wheel I98. Pawl 2I0 is urged into engagement with ratchet wheel 208 by coil spring 2I6. Arm 2I2 has on its end an off-set pin 2I8 carrymg a roller 220 which engages the peripheral surface of a cam disc 222. Cam disc 222 is rigidly mounted ain drive shaft 8. c axial with and extending into the hollow inner end of drive shaft 8 is a shaft 224. Keyed on this shaft is a disc 226 having a clutch face opposite a facing 228 on cam disc 222. Rotat able on shaft 224 is a sleeve 230 havm g a gear 232 in engagement with gear 206. Rigid with sleeve 230 is a disc 234 having a clutch face 236 engageable with the face of disc 226 opposite clutch face 228. A coil spring 238 arranged in the hollow end of shaft 8 urges shaft 224 to the right (Fig. 14), On the face of disc 228 are magnets'240 connected by suitable brushes 242 and an electric circuit to a counter 244 mounted on shaft II 0 to count each revolution of the machine and therefore each setting of a scoop on the tape.

Tape feed roller I98 is mounted on an off-set or eccentric portion 246 of shaft 2I4, and this portion carries ahand lever 248. A coiled fiat spring 250 has one end secured to shaft 2I4 and the other to a fixed pin 252 so as to tend to turn shaft 2I4 in a counter-clockwise direction (Fig. 2) so as to press said roller I98 against feed roller I96.

The mechanism above described operates as follows:

Shafts 8 and I2 are driven at the same speed. In each rotation of shaft I2, block 68 is reciprocated and knife 88 moves downwardly past fixed knife 66 to shear off a scoop blank. Because of the pressure exerted, this blank will be held in position on projection of knife 88 until removed therefrom in a manner to be described below. After knife 88 returns to its upper position,- clearing fixed knife 68, the mechanism shown particularly in Figs. 3 and 6, operates to advance feed wire wheels 32, 38 by one step. This is accomplished by the fact that crank pin 20 shifts pawl 22 alternately to the left and right in Fig. 3 so as to impart a step by step rotation to Wheel 36 and therefrom through shaft 28 to wheel 32 and through gearing 30, 38 to wheel 38. The pressure on the wire can be adjusted by turning wheel 58 which limits the rocking of shaft 34 and thereby the movement of feedwheel 38 towards wheel 32.

Each rotation of shaft I2 also imparts a com plete rotation to shaft I8 and a complete oscillation to lever I08 and thereby to segmental rack I I6. This oscillation causes oscillation of gear II8, and through this gear oscillates shaft I20. Because however of the provision of notches I22 (Fig. 18) there is a period of dwell at the end of each oscillation of gear I I8 in either direction, so that during a part of the time shaft I20 remains stationary.

Assuming now that the parts are in the position shown in Fig. 170, and that the key I24 is in the position shown in Fig. 18, and that shaft I20 is turning in a counter-clockwise direction (that is, that the dwell at the beginning of the counter-clockwise rotation is ended) the parts operate as follows: Discs I28 and I 32 forming the drum start to rotate counter-clockwise. In the position shown in Fig. 17C, die holder I 40 is engaging the rear or counter-clockwise wall of recess I38. The side tools or clamping levers I18 have been shifted inwardly towards each other against a scoop, and also shifted inwardly towards the drum mechanism so that the tape is advanced towards the radius of that mechanism.

As the counter-clockwise rotation of the drum mechanism starts, cam surface I gradually allows the side tools I18 to shift apart at their inner ends. At the same time, flat surface I88 moves out of the path of the noses or inner ends of these side tools so that the same are shifted away from the axis of the drum mechanism to move the tape away from this axis. During the counter-clockwise rotation from the position shown in Fig. 17C, friction member I64 causes die carrier I40 to turn with discs I28, I32 to a position spaced away from punch member I48. By the time die holder I43 together with the scoop 262 carried thereby reaches a position to engage .stop L84, :thetape and :the side-tools have been moved completely away from the path of the-puneh-member. Theparts continue to more fmmtheposition shown :17-(3 in encounter..- clockwise direction to that shown in Fig. .179. At this-point, projection .140 of .carrier 188 engages stop ,tfifiwhich prevents its funthercouirten clockwise .movement. Upon the icont-inued 11mm: ingot .cliscs 1:28, l 32, :the .carrier 1.36 remains stat tionary, "friction member 164 sliding .on its .sur-. face. As soon as the carrier reaches this Stfi! tionary position, the .knife 'feeds a scoop blank (indicated in Fig. 170 at 260) into the recess A .of the Edie block I412. At substantially .the moment that the knife reaches its lower position, .punch member 1.4.8 which has continued tOftLllI-l with discs L28, .=I.:32 reaches the position shown in Fig. 17A. 'When it does this, punch I152 engages thehead portion ofthe scoop blank opposite recess lit and shapes thehead of the scoop to f rm a protrusion on one side and .a recess 9. .1 the .otherof any suitable type to inter.- lookiwith similar protrusions and recesses on an opposing fastener stringer.

-A=t intervals it is necessary to provide. a larger gap sothat groups of scoops on'thetape will :be separated by spaces of considerable length. For this purpose, a counter 244 which counts each revolutionof shaft Hi operates after a set :nu-me her of rotations of this shaft to energize a :solenoid or magnet 248 011 disc 222 turning with shaft 8. This -magnet attracts to it clutch disc 2 26 and disc 234, so that these-two turn atthe same speed as shaft 8. This drives (gear 232 which in turn rotates gear 2-05 rigid with shaft 282, so that tape feed wheels 1%, 493 instead of 'being advanced merely one step for each rotation of shaft "8 are turned rapidly through a substantial angular inter-val so as to form a gap in the tape before the next scoop is set.

After onerevolution, or a predetermined number of revolutions, of the counter shaitii. e., of shaft .119), the solenoid or magnet is deenergized and spring 2 33 separates discs {2'25 and from dis .22 so t a ep y p ra n i the eedin mss ni m is r m dh dimensions of gears 20 5, 232 will determine the-dength of the gap between groups of scoops.
